Hiring a developer is one thing. Hiring the right developer—someone reliable, skilled, and aligned with your project goals—is another challenge entirely.

Today, as more businesses seek tech talent from Nigeria, the need to properly evaluate developers before making a hiring decision has become even more important.

The rise of remote work, rapid digital transformation, and the growing pool of Nigerian tech talent make it an exciting time to build digital products—but also a time to be extra intentional about how you assess the people behind the code.

At Charisol, we’ve seen firsthand how choosing the right developer can make or break a project. Our founder, Dolapo Olisa, transitioned from mechanical engineering into tech because he saw how digital solutions could transform businesses. That same passion drives our work today—connecting skilled Nigerian developers with small businesses and startups across the world and ensuring both sides succeed.

If you’re thinking of hiring a Nigerian developer, this guide will show you practical, straightforward ways to assess their skills and make confident hiring decisions.

Why Testing Developer Skills Matters More Than Ever

A beautifully designed resume or polished LinkedIn profile doesn’t always equal technical competence. Skill testing helps you:

  • Avoid hiring someone who can’t deliver what they promise.
  • Ensure the developer truly understands your tech stack.
  • Reduce project risk and unexpected delays.
  • Verify communication ability and problem-solving skills.
  • Build long-term confidence in your digital product team.

And when working with a global talent pool, especially across time zones and varying levels of exposure to international standards, testing is one of the most reliable ways to ensure high-quality results.

Practical Ways to Test the Skills of Nigerian Developers Before Hiring

Below are methods we’ve used over years of working with developers across Africa and delivering digital products for clients in the UK, the US, Canada, and Nigeria.

Each method is practical, fair, and designed to give you a true sense of a developer’s capabilities.

1. Begin With a Clear, Short Technical Screening

Before giving a heavy technical test, start with a simple first step:

  • What programming languages do you work with?
  • What tools or frameworks have you used recently?
  • Can you walk me through a recent project you built?
  • How do you handle debugging and testing?

A 10–15 minute screening call helps you quickly filter developers who may not match your tech stack or experience level.

Look for clarity, confidence, and ownership of past work. Developers who have truly built things usually explain them naturally.

2. Use Practical Technical Assessments, Not General Trivia

Instead of generic, academic-style questions, use hands-on assessments that reflect the actual tasks they’ll handle in your project.

Examples:

  • A small feature build (API endpoint, UI screen, dashboard component)
  • A debugging challenge
  • A code review exercise
  • A short UX task for frontend or product-focused developers

Keep it short, realistic, and relevant. The goal isn’t to overwhelm them—it’s to observe how they think and build.

This approach usually gives you more truthful insights than long theoretical quizzes or LeetCode-style tests.

3. Review Their Past Work Deeply, Not Superficially

A good portfolio tells a story. Review it with intention.

Look for:

  • Code samples or GitHub links
  • Real, functioning product examples
  • Contributions to previous projects
  • Visible growth over time
  • Consistency in design, logic, and execution

If they worked on a team project, ask:

  • Which specific part did you build?
  • What challenges did you face?
  • What decisions did you make and why?

Genuine developers can easily discuss the details of their past work because they lived it.

4. Check for Problem-Solving Ability, Not Just Coding Skill

The best developers aren’t just people who write code—they solve problems.

Ask scenario-based questions like:

  • If a user reports a bug but you cannot reproduce it, what steps do you take?
  • How do you estimate the time for a task you’re unfamiliar with?
  • What do you do when you’re stuck on a technical problem?

You’re assessing their thinking pattern, not memorized answers.

Skilled professionals show curiosity, patience, and structured reasoning—core qualities of a dependable developer.

5. Test Soft Skills, Especially Communication

Soft skills matter just as much as technical skills, especially when building products remotely.

Evaluate:

  • Do they explain technical concepts simply?
  • Are their messages clear and timely?
  • Do they ask clarifying questions?
  • Can they give status updates without being reminded?

Good communication prevents misunderstandings, delays, and unnecessary tension.

At Charisol, we’ve learned that empathetic communication is one of the strongest predictors of long-term success—aligned with our core values of collaboration, honesty, and grace.

6. Run a Paid Trial Task Before Committing Fully

A paid trial is one of the fairest and most accurate ways to test a developer in real conditions.

This could be:

  • A small feature development
  • A bug fix
  • A simple UI layout
  • A backend integration
  • A UX wireframe or design task

A paid trial allows you to observe:

  • Code quality
  • Speed and responsiveness
  • Communication style
  • Attention to detail
  • Reliability
  • Compatibility with your workflow

Paying for the trial also shows respect for the developer’s time and aligns with Charisol’s value of leading with integrity.

7. Conduct a Cultural Fit Assessment

Great products are built by teams who align on values and work style—not just technical knowledge.

Ask questions like:

  • What kind of work environment brings out your best self?
  • How do you handle feedback?
  • What type of projects energize you?
  • When you make a mistake, what do you usually do next?

Aligning expectations early prevents project breakdowns later.

8. Validate Their Professionalism and Work Ethic

Professionalism is a skill. Test for:

  • How they respond to deadlines
  • Their approach to task management
  • Their independence vs. need for handholding
  • How they document code or designs
  • Their respect for confidentiality
  • Their accountability when things go wrong

Strong developers show consistency and reliability, not excuses.

9. Check References and Testimonials

A quick reference check can save you months of stress.

Ask previous clients or team members:

  • Was the developer reliable?
  • What challenges did you face working with them?
  • Would you hire them again?
  • How was their communication?

The goal isn’t perfection—it’s honesty. A strong developer will have past collaborators eager to speak positively about them.

FAQs About Testing the Skills of Nigerian Developers

Do technical tests discourage good developers?

They don’t—if the tests are fair, short, and relevant. Strong developers appreciate thoughtful evaluations because it shows you take quality seriously.

What if a developer has no portfolio?

Ask for GitHub samples, a walkthrough of past projects, or assign a small paid task. Many talented developers started their careers working on internal products that weren’t publicly visible.

Should I prioritize certificates or real-world skills?

Real-world skills. Certificates help, but practical ability, problem-solving, and communication hold more weight in real product development.

How can I reduce the risk of hiring the wrong developer?

Combine three steps:

  • A short technical conversation
  • A small paid assessment
  • A reference check
    These three together provide a strong picture of the developer’s competence.
